PLEfRf-LISING APRARATUS.

Application filed July 25,

To (11210700772, t may concern- Be it known that L l/Vnne Kmnnnirno, acitizen of the United States7 residing at Norton, in the county of Viseand State of Virginia, have invented new and useful lnk provements inPole-Raising Apparatus, ot which the Jfollowing is a specification.

The obj eet of my said invention is the provisionot an apparatus simplein construet'ion, li gli-t in weight and susceptible olf easy operationwhereby three men are enabled `to raise poles such as telephone andpower line poles and pull out old wooden poles with a minimum amount olieffort.

rllhe apparatus is also equipped. to avert injury to the wall of a polehole by guiding a pole into the hole, is adapted to be readily takendown, and is also adapted to be con veniently carried trom one pole holeto another. l

To the attainment ot the foregoing3 the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanyingdrawings7 forming part of this specification Figurel. is a side elevation, partly in section and partly broken away showing`my novel apparatus as arrangeditor the raising ot a pole.

` My invention contemplates the raising` of the main pole by one manmanipulating the cranlihandle G while two other men steady the pole withspike poles or hand lines (not illustrated) ifi/*hen the main pole is inupright position it, isln'aeed through the medium of two ad justablebraces, and a wooden brace 7 is employed 'tor steadying and raising themain pole and the apparatus as a whole. One of the adjustable braces isshown in Figure l and designated by 8, and ,l would have it understoodthat the other adjustable brace 8 at the opposite `side ot the main poleis similar tothe one shown in Figure I1.. The brace 8 ol" Figure l ismade up o't an upper section i) oi' gas pipe, a lower section l()preferably oi1 Airon pipe and pointed at its lower end l1, a metalliccollar l2 and set screws 13. Mann iestly lthe said brace 8 is adapted tobe readily ii'uzreased and diminished in length and the' section l() isadapted to be lixed to the section 9 in a strong manner by the screws1.3 which extend through the collar l2 and the section t3 and are setagainst the section 11.0. The adjustable capacity ot the braces 8 adaptsthe apparatus ior use on various surtaces and hence the apiniratusy maybe used to advantage on hill sides and on level tracts. In order `totake down the timber or main pole member `2, the uppermost bolt t isremoved, and the bolt 4t below the uppermost one ,is utilized as a pivotfor the upper member 2. lVhen short poles are to be raised the lowermember' or timber l oft' the main pole need not be employed.

Connected by a bolt 14 to ythe lower member l oit the main pole is aU-shaped member l5, and appropriately connected at lo to the said memberl5 is a pole guidel 1T, ot sheet metal. or other impropriate material.rlfhe said guide ll being adapted to depend into a pole hole designatedby 18 in Figure l and 'to rest adjacent to one wall 19 ol the pole holeso as to guide the lower end of the pole to be raised, designated by 20,into the hole and at the same time avert caving in or injury to the saidside ot the hole 18 incident to the raising ot the pole. By removing thebolt or bolts let the guide 1T and its appurtenances can be easilydisassociated Ytrom the member l. ot'the main pole.

rlhe braces tl are by preference pivotally connected to the member Q otthe main pole, as designated b v Qtr and the wood brace 'T is providedat its upper end with one or more straps 22 of iron on Which are hooks23 to engage studs 24 provided on the sides of the member 2, Figures land 2. Manifestly the wood brace is adapted to be quickly and easilyengaged with andvdisengaged from the main pole member 2,

At 24 the device is provided with metallic handles so that the device orapparatus can` be conveniently carried. i

At the top of the main pole member 2 a sheave is provided, the saidsheave 25 being mounted between the extended portions strap irons 2G,fixed at 27 to the member :2, andthe said sheave being disposed underand protected by a cap 2S Whichis mounted on the strap irons 26 as shownin Figures 1, 2 and 6.

.fr flexible steel cable 3() is employed as a part o'lE the apparatusand is designed to be tied `around a pole 20, as indicated by 31 inFigure l. The said cable is passed over the shcave 25, and is thencarried down- 'u'ardly and adapted to be Wound on a drum 32, .Figures 2,4 and 5. The said drum 32 is appr n riately Fixed to a shaft 33 on whichare also lined brake disks 234; and it will also be noted that the saidshaft 33 is journaled in bearings 35 and is equipped at 236 with a largespur `gear, the saidspur gea;` being associated with 'a gravitationaldetent 37 for preventing retrograde rotation ther-ooi". The bearings 85are carried by upright 'traine members 40 as are also loiver bearings 4land the bracket arm 42to Which the bet-'ore mentioned detent 37 ispivoted. in the lower bearings 4l a shaft 43 is journaled, and thissha-Et 43 is adapted at .one end for the application olf the beforementioned crank 6, and is equipped with a spur gear 44, intermeshed withthe before mentioned large gear 3G. Blocks 45 are interposed bet-Weenthe bearings alluded .to and the upright frame members 40, and Athebearings, blocks 45 and the upright members 40 are vfixedly connectedtogether Vthrough the medium of bolts on which are ailipropriate nuts5l. lt will also be noticed` that the uprights 40 are maintained inproixier relation to the loiver main pole member l through the medium ofmetallic straps GO. said straps GO being fixed at the lower and upperends ot the members40, and being arranged at opposite side of the mainpole member l, and-provided with bolts Gl at opposite side of said mainpole member.

Carried by the blocks 45 is a rock shaft to which is fixed a lever 71.Also fixed to the rock shaft T() are arms 72, the said arms 72 beingconnected to certain ends of brake bands 73; the other ends of Which areconnected to studs 74 carried on the blocks 45. lt will be readilymanifest that incident to the raising oi pole by the turning oit the`crank, the operator Who turns the crank is enabled. at. any time toconveniently brace on the angular lever 7l and thereby apply the brakeband 73 to theidisks 34 so as to preclude a fall of the polethat -isbeing raised.

l ln the present and preferred embodiment ofimy invention the uprightmembers 40 are aliipropriately lived to a base 40X, Fig ures l and 2,the said base 4()X being provided with spikes 41X, designed to beembeddedin the ground after the manner illustratedivitlr a view toprecluding casual movement of the lower end of the apparatus wheny thesame is in use.

In addition to the practical advantages ascribed to my novel apparatusit Will be noted ,thatthe apparatus is simple and inexpensive inconstruction and is well adapted to withstand the rough usage to whichapparatus ofcorresponding character is ordinarily subjected.

Iny virtue of its yconstruction my novel apparatus is also adapted to beused to advantage 'for-placing, heavy load on trucks and Wagons.

I have entered into a detailed description o'l` lthe construction andrelative arrangement ot the parts embraced in the present and 1n'eferredembodiment of my invention. incr-del to impart a full, clear and exactunderstanding ot the said embodiment, l d0 not desire, however, to beunderstood Ias confining myseltl to the spec'lic construction andrelative .arrangement ot parts inasmuch. as in the 'future practice ofthe in vention various changes and modifications maybe made such as fallWithin the scope et my invention as defined in my appended claims.
